    Hello,
    I have spent some time looking at previous posts and trying stuff.

    My tablet boots first with the COBY screen and then the Android screen, at this point nothing else happens. I have done a reset using a paper clip.

    I suspect it got in this state when i was restoring a backup from an app, the files were meant to go to removable storage but i think they may have gone to the internal drive by mistake. This is only hypothesis though !!

    What i have done so far:-
    1) installed usb driver to communicate to the tablet from pc. That was an ordeal as using the android sdk drivers do not install unless the ID strings are tweaked to match the ones expected from the tablet.

    from "android_winusb.inf"

    [Google.NTx86]


    ;Coby MID-1125
    %SingleBootLoaderInterface% = USB_Install, USB\VID_18D1&PID_D00D
    %SingleAdbInterface% = USB_Install, USB\VID_18D1&PID_D00D
    %CompositeAdbInterface% = USB_Install, USB\VID_18D1&PID_D00D
    %CompositeAdbInterface% = USB_Install, USB\VID_18D1&PID_D00D&MI_01
    %CompositeAdbInterface% = USB_Install, USB\VID_18D1&PID_D00D&MI_01



    2)Reset the tablet into its debug mode by holding the volume button down on reset. I get the prompt at the bottom left of the screen.

    3)Run "Fastboot" . This communicates with the device. I can reboot it and clear the user/cache ok.

    4)Used the "Patch_1125_v2" to use fastboot to install a "Unsecure_1125.img" and reboot. This works ok

    5)After reboot i run the adb program but get "device not found"


    D:\ANDROID STUFF\Patch_1125_v2>fastboot flash boot Unsecure_1125.img
    sending 'boot' (5616 KB)... OKAY
    writing 'boot'... OKAY

    D:\ANDROID STUFF\Patch_1125_v2>fastboot flash recovery Recovery_1125.img
    sending 'recovery' (6760 KB)... OKAY
    writing 'recovery'... OKAY

    D:\ANDROID STUFF\Patch_1125_v2>fastboot reboot
    rebooting...


    D:\ANDROID STUFF\Patch_1125_v2>adb devices
    List of devices attached


    D:\ANDROID STUFF\Patch_1125_v2>adb start-server


    What can i do now ?? I emailed COBY usa and have received diddly squat.
    The hardware must surely be ok to get this far.

    I am now stuck, i can't believe how fiddly it is to get back to a known state. On a pc you can boot from another device when all else fails.
    I wondered if it is a simple matter to open up the back, take the sdcard out and re-create an image on it using a basic device like a camera or dictaphone ?

    thanks in advance.

    Got a bit further ..............................

    Once the tablet has booted, looked at PC device manager and "gingerbread adb" was shown in yellow - needs a driver.
    Checked the ID and it is slightly different to what i assumed. Changed the inf file and driver installed ok.

    Fastboot is PID_D00D and ADB is PID_DEED



    ;Coby MID-1125
    %SingleBootLoaderInterface% = USB_Install, USB\VID_18D1&PID_D00D
    %SingleAdbInterface% = USB_Install, USB\VID_18D1&PID_DEED
    %CompositeAdbInterface% = USB_Install, USB\VID_18D1&PID_DEED
    %CompositeAdbInterface% = USB_Install, USB\VID_18D1&PID_DEED&MI_01
    %CompositeAdbInterface% = USB_Install, USB\VID_18D1&PID_DEED&MI_01


    So now ADB is communicating:-

    D:\ANDROID STUFF\Patch_1125_v2>adb devices
    List of devices attached
    0123456789ABCDEF device



    What do i do next folks ???

    during bootup

    adb shell logcat

    what os are you running, you posted a lot of info but none is of any help.

    start by posting the version of android you are using, what app you restored and if the device was rooted, and how it was rooted, did you use CW recovery to make a backup?

    unless you are building a kernel and what to debug the kernel the above has no use.

    logcats are important debugs aren't

    Hello Vampirefo,

    I am a total noob with tablets. in fact i deserve a chocolate medal to get this far.
    I have sparse linux knowledge.


    I am not trying to root the device, it just stopped working and i am try to get back to using it.
    I think the android version is icecream. I had no backups of the system when i got the device (i have now!).
    If you tell me what to do, i can run the commands.


    D:\ANDROID STUFF\Patch_1125_v2>adb shell logcat
    /sbin/sh: logcat: not found

    you got lots of problem then, Unsecure_1125.img is a 2.3 kernel (gingerbread) and it's unable to boot 4.0 (icecream)

    post output of below

    adb shell

    cat /system/build.prop

    You need to get a 4.0 kernel and flash it.
